Should I keep or return Genki I?

Well, to be fair. This is why I haven’t got myself a copy of this book. So what I’ll say is just my opinion since I’ve only studied using Minna no Nihongo

I’ve come across a lot of topics here about Genki books and the major opinion is that they are great, even if you are a self learner so if you have already bought em. I’d say keep em

There is, by the way a course from the MIT here in the forums using Genki, with enough people it might become a classroom.

Genki genki
